åAfter several days of wildfire activity over parts of northern British Columbia (BC), northern Alberta (AB), and the Northwest Territories (NWT) of Canada (which produced a great deal of smoke, but no pyroCb activity), the conditions of the synoptic-scale environment became more favorable on 14 July 2014, allowing multiple pyroCb events (at least five?) to […]
On 07 June 2014, McIDAS images of 1-km resolution GOES-15 0.63 µm visible channel and 3.9 µm shortwave IR channel images (above; click image to play animation) showed that the Two Bulls Fire just west of Bend, Oregon (station identifier KBDN) began to burn an area large enough to be detected by satellite around 20:00 […]
On 15 September 2013, a Pyrocumulonimbus (PyroCb) was detected by GOES-15 imagery in British Columbia, Canada in the center of the province. The animation above is imagery from GOES-15 (click animation to play); the panel on the left is the visible bandwidth and the panel of the right is shortwave infrared bandwidth highlighting the fire hot-spots […]
As the Rim Fire continues to burn near Yosemite National Park in California on August 21st, 2013, another pyrocumulonimbus has spawned from the complex. Looking at the GOES-15 visible imagery (above, left; click image to play animation), a large plume of cloud can be seen erupting from the fire, centered approximately at 38N 120W, at about 22 UTC. […]
Mike Fromm (NRL) coined the term “pyrobubbles”, and pointed out 3 examples that occured on 16 August 2013. We shall examine each of thse 3 cases using GOES-15 (GOES-West) imagery. The first pyrobubble originaled from a fire near the Idaho/Montana border; GOES-15 0.63 µm visible channel images (above; click image to play animation) showed the […]
Sparked on Saturday, August 11, the Tooele County wildfire continued to burn through Wednesday, August 14, belching a large amount of smoke into the atmosphere. GOES-15 visible imagery (above, left panel; click image to play) depicts a fair amount of smoke being ejected from the fire and a small pyrocumulonimbus cloud forming rapidly near the end of the […]
